"Republicans just don't do this kind of thing," Limbaugh claimed during his radio show. "Even though every event, like mass shootings, remember, every mass shooting there is, the Democrats in the media try to make everybody think right off the bat that some tea partier did it, or some talk radio fan did it, or some Fox News viewer did it. Turns out, it's never, ever the case," Limbaugh added, without evidence.

Limbaugh added that none of the bombs went off before suggesting, also without evidence, that a "Democrat operative" was attempting to create the appearance that there "are mobs everywhere."

The conservative commentator later said he would not let the reports of the bomb threats distract him from stories such as the migrant caravan traveling toward the U.S.-Mexico border and what he called the "declining blue wave" as the midterm elections near.
